Seriously cheap construction but good value for money. So far everything is fine with the sound, but it did not break and was not installed. The hardware holding the speakers in place snaps out instantly when tightened, even when the coupler is used on a power drill. It may be worth using hand tools and gently tightening. I've installed many in-wall speakers over the years and these are the cheapest I've tried. You get what you pay for, but the overall look and sound quality add value here. I installed them to replace my ugly and not very good sounding Bose Acoustimass 15 cubes.
